SPECIFICATION forming part ornate... Patent No. 584,675, dated June 15,1897. Application filed February 27, 1896. Serial No. 580,997. (Nomodel.)

To aZZ whom, it may concern:

Be it known that we, CHRISTIAN DANCEL, residing at Brooklyn, in thecounty of Kings, and JACOB R. Sdo'rnresiding at New York, in the countyof N ew York, State of New York, citizens of the United States, haveinvented new and useful Improvements in Sewing-Machines, of which thefollowing is a specification. r

' The object of this invention is to obtain a machine serviceable insewing boots and shoes and adaptedto secure an improved quality of work;and the invention resides in the novel features of construction setforth in the following specification and claims and illustrated in theannexed drawings, in which Figure 1 is a front elevation of asewing-machine. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is asection along line it it, Fig. 1, showing the looper and looper-cain.Fig. 4 is a section along line o C, Fig. 1, showing the awl and theneedle and needle-cam. Fig. 5 is a section along line w to, Fig. 1,showing the take-up and take-up cam. Fig. 6 is a section along line a;m, Fig. 1, showing the thread-Ineasurer and the thread-measurer cam.Fig. 7 shows a loop-carrier. Fig. 8 shows the needle as having passedthrough the work and receivinga loop of thread. Fig. 9 1 shows a frontelevation of the needle as'having drawn out a loop of thread. Fig. 10shows a side elevation of the shuttle, the loop-carrier, and of theneedle as having drawn out a loop of thread. Fig. 11 shows asideelevation of thcloop-carrier having carried the loop over the shuttle.Fig. 12 is a side elevation of Fig. 11. Figs. 13 and 14 show a take-uplever.

The column 1 supports a plate or base 2 and stands or bearings 3 for theshaft 1, having the pulley or driver 5 and provided with cams foractuating various parts. The work support 6 has a hollow or chambered orpreferably frame-like support consisting of the legs 7, giving access toas well as room for the motion of the and 8, the looper 9, andthreadmcasurer 10. The work, such as a boot or shoe with its upper 11,its outsole 12, and its insole 13, being supported on the work-plate 6,the awl 8, passing through a slot or throat socket. or carrying-arm 28.

track 28. i

in plate 6, pierces the work 13 12, after which theawl returns into thesupport 6 7, and the needle 14, entering the hole pierced by the awl, issupplied with th read by looper 9. The needle seizing and drawing outthe loop of thread, such loop is enchained, if the machine produces achain-stitch, or, what is thought preferable, the loop is locked bythread from thread-case or bobbin-holder 15.

By having the shoe or work support made to enter the shoe or Work andthe awl made to act from the support to the shoe or work and outwardthrough the latter anybur or roughness caused by the piercing will beformed on the outside of the Work, leaving the interior smooth andcomfortable to the touch.

The awl has a piercing motion or-reciprocation and also a feeding motionor reciprocation. The piercing motion is effected by groove or cam 16,Fig. 3, engaged by stud or roller 17 of lever 18 19, fulcru med at 20and carrying a gear or toothed segment 21, en gagin g gear 22 ofrock-shaft 23. This rock-shaft 23, by an eccentric 24 oreccentrically-studded disk 25, reciprocates link 26, with slide 27,carrying the awl 8 or the awl-carrying The slide 27 reciprocates in away The feed-motion of the aWl is obtained by reciprocating this way orThe track or arm 28 extends from or forms part of a rock-sleeve 29,Figs. 2 and 3, sitting loosely about rock-shaft 23, so that the sleeveand arm can rock independently of one another. Fron'i sleeve 29 extendsan arm 30, Figs. 1 and 2, having slot 31, from which extends stud 32into slot 33 of arm 34 of lever 34 35, fulcrurned at 36 and actuated bygroove or cam 37. The track or arm 28 extends suitably into thework-support 6 7, and as this arm 28 is reciprocated by sleeve 29 andarm 30 a feeding reciprocation or stroke isimparted at proper moments tothe awl carried by or sliding on arm 28. By setting the stud or pivot 32along slots 31 and 33 toward or from sleeve 29 the feed-stroke of arm 28and awl 8 is regulated.

The eye or looper 9 has, as known, a fourinotion stroke or a lateral aswell as backand-forth motion to loop the thread onto the needle orneedle-hook. This looper is carried by or forms part of a lever 38,Figs. 1 and 3, havingits fulcrum or pivot 39, carried by arm 28, so asto partake of the lateral motion or reciprocation already described ofthis arm 28. The lever 38 connects by link with lever 41. 42, fulcrumedat 43 and actuated by groove or cam 44. The looper 9 being reciprocatedback and forth by leverarm 41 and accompanying arm 28in its lateralreciprocations executes the requisite four-motion or looping stroke. Toprevent breakage or secure easy motion, the link 40 is shown connectedto lever-arm 41 by aball-and-socket joint.

The thread-measurer 10 is carried by or forms part of a lever 45, Figs.1 and 6, also fulcrumed at 39 on arm 28. Lever 45 connects by link 46with lever 47 48, f ulcrumed at 49 and actuated by groove or cam 50.Link 46 advantageously connects with lever-arm 47 by a ball-and-socketjoint. The action of lever-arm 47 gives the thread-measurer itsback-and-forth or measuring stroke. By having the thread-measurer withlooper 9 carried by laterally-reciprocating arm 28 said thread-measurerwill accompany orkeep near to the looper in its lateral strokes.

The thread-case 15 has a bobbin 51, Fig. 5, which is free to be rotatedin the thread-case by the draft on the thread to deliver or unwindthread. The thread-case 15 is stationary and is seated in a box orreceptacle 52, Fig. 1, surrounding the thread-case sufliciently to keepthe latter from falling or rolling out away from the needle 14. Thethreadcase is held in its box by an arm 54, the free end of whichengages a shoulder on the shuttle. This arm 54 extends from a rock-shaft56, Fig. 5, having arm 57, engaging groove or cam 58, Fig. 1, so that atsuitable moments the arm 54 is rocked or swung to lift its free endsufiiciently clear of thread-case 15 or of nose 55 to allow aneedle-thread loop to be passed over the thread-case. The engagement ofarm 54 with nose 55 prevents the threadcase 15 from rotating.

The loop-carrier 59, Figs. 1, 5, 7, 9, 10, 11, and 12, extends from arock-shaft 60, carrying arm 61, Figs. 1 and 7. The link 62, Fig. 1, isjointed to arm 61 and to arm 63 of lever 64, fulcrumed at 65 andactuated by groove or cam 66. The rock-shaft 60 is journaled in sleeve67, Figs. 1 and 5, which is carried by arm 68, Figs. 1, 6, and 7,extending from lever 69, fulcrumed at and actuated by groove or cam 71.lVhen the needle has drawn up a loop of sewing-thread, the rockshaft 60is moved to swing the loop-carrier 59 into said loop, so as to lift orfree the loop from the needle-hook and cause said loop to rest on orstraddle the carrier 59, at the same time becoming somewhat spread. Thelever 69 being then actuated to swing or move the carrier with the loopover the thread-case 15 and the rock-shaft 60 being then swung to bringthe loop-carrier 59 to releasing position or to such dip that the loopslips off the carrier, said loop is free to be drawn through between thethread-case 15 and its seat 52 and to be then drawn in to complete orset a stitch. In entering the loop the carrier 59 also spreads the same,so as to secure the straddling of the thread-case by the loop. The arm54, as before noted, being temporarily or momentarily raised at theproper moment the loop-thread can pass between the arm 54 and thethread-case 15.

The needle 14 is suitably mounted, as on a carrier 72, Fig. 4, actuatedby or geared to lever 73, fulcrum ed at 74 and engaging groove or cam75.

The take-up-actuating lever 76 77, Fig. 5, fulcrumed at 78 is actuatedby groove or cam 79 and connects by link 80 with an arm 81 of athree-armed lever or take-up 81 82 83, fulcrumed at 84. The take-upcarries apulley or roller 85, Figs. 2 and 3, and an arm or lever 86 isfulcrumed or pivoted at 87 to the take-up. This arm 86 carries a roller88, and a spring 89, secured to the take-up arm 83, acts on the tail orstud 90 of arm 86. The tendency of spring 89 is to move roller 88 in adirection away from the work-support 6 or needle 14. From tension 91 thesewing-thread 92, Fig. 2, passes by or about rollers 85 88 to thework-support. A motion or swing of arm 82 83 to carry roller 88 awayfrom the worksupport and to carry roller 85 toward the work-support willtake up or tighten a stitch and also draw thread for a succeeding stitchfrom tension 91. The arm 86, forming a supplemental take-up, aids orsupplements the action of the take'up 81 82 83, as required.

The action of the machine will be readily understood. The awl 8 havingpierced the work and also fed, if required, and the thread 92 having hada certain length 93 94, Fig. 8, measured off by thread-measurer 10, theneedle 14, descending or entering into the hole left by awl 8, has thethread portion 93 94 hooked or engaged thereto by looper 9. The

needle then rising or returning draws out the sewing-thread loop 93 94,Fig. 9,which is taken by loop-carrier 59 off the needle-hook and overthe thread-case 15, Fig. 9, to be then drawn in by the take-up andlocked by the thread-case thread 95. A presser-foot 96, Figs. 1- and 2,extends from plate or carrier 97 on the segment 98 on pivot or shaft 99and having a handle 100. A spring 101 tends to hold or move thepresser-foot to the work or throat plate 6. The segment 98 has a ratchet102, which when engaged by pawl 103 looks or holds the presser-foot tothe work. The pivot 99 is mounted on a plate 104 105, Fig. 3, forming alever fulcrumed or centered at 106. The spring 107 presses on lever armor plate portion 105.

At every revolution of the machine the pawl 103 is unlocked to free thepresser-foot for allowing the work to be fed. The lever 108, Fig. 2,fulcrumed at 109, has a stud 110, made to abut against or release thepawl 108. The lever 108 is actuated by groove or cam 111, so as towithdraw or release the pawl 103 at suitable periods. The pawl 103 underthe push or tension of spring 112 normally tends to assume a lockingposition or to engage ratchet 102.

- The lever 108 has a tail or arm 113. When the lever 108 movesthepawl103 to releasing position, the tail 113 is forced against thepresser-foot carrier 98 and lifts the presserfoot or channel-guide oit'the work or against the resistance of the spring 107 to allow easy feedof the work. In general it may be found of advantage to have twoloeking-pawls 103 alongside one'another to engage ratchet 102.

The machine it is noticed is serviceable in sewing shanks after the lasthas been taken out, said machine, as seen in Fig. 12, being serviceablefor uniting the insole, outsole, and upper of boots and shoes bystitches, or making shoes with welted fore parts and stitched shanks,but of course the machine is not confined to such specific uses, as itcan be employed wherever serviceable.

It will be observed that in our invention the thread-measurer executesits measuring stroke wholly at one side of the line of sewing and in adirection from the line of sewing outward or away from themachine-frame. Thisis advantageous in that the thread-meas urer iseffectually prevented from coming in contact with the work or shoe,because the measuring stroke is made from the side or end of the work ator near which the sewing is being effected toward the other or oppositeside or end of the work.

By having the lever81 82 83 provided with the third arm 82 such thirdarm can enable an increased take-up to be effected, as by supplying suchthird arm 82 with a pulley 114, Fig. 13, about which the thread can beled. In Fig. 13 the supplementary lever, as shown at 86, has a secondarm 115, with pulley 116, and the thread passing by the pulleys 85, 116,SS, and 114 can have a considerable take-up imparted thereto by theactuation of said three-arm ed lever.
